Dhritarashtra who lost all his sons in the Kurukshetra war
in the Mahabharata was treated with respect and love by Kunti and the Pandavas.
The blind king was taken care well by the Pandavas. But Bhima, the second of the Pandavas, never forgave the
old king for what he and his sons had done to him and his family. Whenever
there was opportunity, Bhim reminded Dhritarashtra how he had killed each of
his hundred sons.

One day Vidura, the minister of Hastinapura and uncle of
Pandavas and Kauravas, who had gone on a pilgrimage during the Kurukshetra war
returned back.

Dhritarashtra was missing his brother. After a few days, the
wise Vidura reminded Dhritarashtra that it was time for him to take Vanaprastha
– abandon city life and head towards the forest.

But Dhritarashtra was not ready to abandon the comforts. He
was still enjoying the comforts of life in old age.

Vidura then advised him how death was fast approaching him.
He also warned him that he should make use of what little time was left for
attaining moksha or liberation.

For the first time, Dhritarashtra listened to the advice of
Vidura and left for the forest along with his wife.
